From earlier whirlpoole, whirlpole, apparently from Middle English *whirlpole, potentially coalescing Old English hwierfel (“whirlpool”) and Old English hwierfepōl (“whirlpool”). Equivalent to whirl + pool. Cognate with Scots quhirlepole, whirle-pule (“whirlpool”). Compare also English whirlpit. Eclipsed non-native Middle English gurges (“whirlpool”), borrowed from Latin gurges (“whirlpool”).
